Failed to acquire the lock

[amandeep0440]

Hi,

I am getting the below error sometimes, when i am trying to add about 1.5 million objects in the map using about 20 threads. each thread fetches a list of objects and adds it to the map: dataList.parallelStream().forEach(data -> offHeapCAMap.put(data.getId(), data));

I am persisting the map to the disk and used by only single JVM. I delete the persisted file every time a new process starts. i.e. it starts afresh.

Map Config:

ChronicleMapBuilder<Long, Data> mapBuilder=ChronicleMapBuilder.of(Long.class, Data.class)
				.name("data-map")
				.averageValueSize(30000)
				.entries(1500000).putReturnsNull(true).maxBloatFactor(2);

ERROR:

I dont think it is related to volume of objects. I noticed its happening with 30K objects too.

I'm also getting the same error frequently. Any solution yet?

[RobAustin]

Where is the chronicle map file stored. Is it on the local disk. ?

[ksiu]

Yes, it's on the local disk

I am getting the same error.. Error is same but at Chroniclemap.compute. I am using 3.14.5 version. Tried to update version but it did not solve the issue. The map is saved to disk in my case ; how to reproduce the issue- This occurs randomly and possibly with a large data set .Any suggestions or workarounds?

@amritkumar123 @amandeep0440 @ksiu could you re-rest now that #376 has been fixed?
