Steps to Reproduce

I believe this problem is relative to size of inserted data, because if inserts data of 0 to 4 offset, crash doesnt occurs.

Short Code Sample

static async test() {
   for (let offset = 0; offset < 999999; offset++) {
     const array = await http request for offset data by 1000 items

     if no data on array, return

     Realm.write(() => {
       array.forEach((item) => {
         Realm.create(`Schema`, item, `modified`);
       });
     });
   }

@kevinpiske

Thank you for reporting. I have a couple of follow-up questions:

Do you only see it on Android? Can you reproduce it on iOS?
What kind of object is item? Properties, values??
Do you also see the crash if you have many small transactions?

@kneth

Do you only see it on Android? Can you reproduce it on iOS?

I am developing only for Android on a Windows machine. Unfortunately I won't be able to test on iOS.

Do you also see the crash if you have many small transactions?

I had no problems with many smaller object transactions, I even tested with about 1 million small records and there was no crash.

What kind of object is item? Properties, values??

The item is from type Schema01. I am currently inserting about 10000 items.

const Schema01 = {
  name: `Schema01`,
  primaryKey: `id`,
  properties: {
    id: `int`,
    prop01: `string?`,
    prop02: `string?`,
    prop03: `Schema02?`,
    prop04: `Schema03?`,
    prop05: `string?`,
    prop06: `string?`,
    prop07: `string?`,
    prop08: `int?`,
    prop09: `int?`,
    prop10: `string?`,
    prop11: `Schema04[]`,
    prop12: `string?`,
    prop13: `int?`,
    prop14: `int?`,
    prop15: `Schema05[]`,
    prop16: `string?`,
    prop17: `bool?`,
    prop18: `int?`,
    prop19: `string?`,
    prop20: {
      type: `string`,
      default: `defaultValue`,
    },
  },
};

const Schema02 = {
  name: Schema02
  primaryKey: 'id',
  properties: {
    id: 'string',
    prop01: 'string?',
    prop02: 'string?',
    prop03: 'string?',
  },
};

const Schema03 = {
  name: 'Schema03',
  properties: {
    prop01: 'string?',
    prop02: 'string?',
    prop03: 'string?',
    prop04: 'int?',
    prop05: 'string?',
    prop06: 'string?',
  },
};

const Schema04 = {
  name: `Schema04`,
  properties: {
    id: `int`,
    prop01: `string?`,
    prop02: `int?`,
    prop03: `string?`,
    prop04: `int?`,
    prop05: `int?`,
    prop06: `string?`,
    prop07: `string?`,
    prop08: `int?`,
    prop09: `string?`,
    prop10: {
      type: `string`,
      default: `defaultValue`,
    },
  },
};

const Schema05 = {
  name: 'Schema05',
  primaryKey: 'id',
  properties: {
    id: 'int',
    prop01: 'string?',
    prop02: 'Schema02?',
    prop03: 'Schema04[]',
    prop04: 'string?',
    prop05: 'int?',
    prop06: 'int?',
    prop07: 'string?',
    prop08: 'string?',
  },
};

Example of item data:

    {
        "id": 000000,
        "prop01": "AAAAAAAAAA",
        "prop02": "00000000",
        "prop03": {
            "id": "000000",
            "prop01": "AAA A/A AAAAAAAAAAA AAAAAA A AAAAAAAAAA",
            "prop02": "AA AAAAAAAAA AAAAAAAAA AAAA, 0, AAAAAAAA, AA",
            "prop03": "00000000000000"
        },
        "prop04": {

@kevinpiske

Thank you for the update.

I had no problems with many smaller object transactions

It indicates an issue in the underlying database, don't you agree @finnschiermer?

finnschiermer · 2020-09-07T14:28:39Z

Yes, I agree. If we can reproduce this it'll be a big step towards fixing it.

We have identified root cause of this, and a fix is being developed.

kneth · 2020-09-10T15:18:55Z

@kevinpiske We have released v6.1.1 with a fix.

kevinpiske · 2020-09-11T15:06:19Z

Thanks all for the fast work!

@kneth, in my case, the problem persists.

Now the stack is not detailed anymore, the log is:
Fatal signal 11 (SIGSEGV) at 0x93242ffc (code=2), thread 9766 (mqt_js)

I realized that the problem occurs when inserting data from two specific schemas. If I comment the inserting data of one these schemas, everything goes well.

The problem only occurs by inserting data of these two schemas in separate transactions. Inserting data of these two schemas in the same transaction, it worked.
