Couchbase Index in warmup

Couchbase Server

Hello

We are using Community Edition 5.0.1 build 5003 and our indexer goes to warm-up state from ready state after a certain duration of time. Unable to replicate the scenario
On search in forums it was asked to look at indexer.log and we find below mentioned error in logs

panic: FDB_RESULT_FAIL_BY_ROLLBACK

goroutine 185 [running]:
panic(0xcbdee0, 0xc496d21ee0)
/home/couchbase/.cbdepscache/exploded/x86_64/go-1.7.3/go/src/runtime/panic.go:500 +0x1a1 fp=0xc4462c76e8 sp=0xc4462c7658

We have sufficient disk space for index
What could be the issue

@srinivas,

Can you paste the complete stack. It is difficult to root cause by just looking at one line of the panic stack trace.

Thanks,

@srinivas,

This issue looks similar to https://issues.couchbase.com/browse/MB-19774 . Looks like a rare race condition has triggered panic during recovery. The second recovery after the panic should succeed.

Thanks,
Varun

@srinivas, you are hitting bug https://issues.couchbase.com/browse/MB-31560. Please upgrade to 5.1.3 or later release. The other bug https://issues.couchbase.com/browse/MB-19774 was already part of 4.5.1 and you are on a later version.
