Jakub\_Jozwicki,

Did you see this immediately after ther server was started. If yes there could be possible race condition where thread which sets up information being accessed by info\_get\_service may not have been initialized. If no then can you please share service section of aerospike.conf you are running with.

Thanks for reporting bug. This will be fixed.

– R

This was in the 2nd hour of stress tests. Configuration bases on default.

```
service {
 [...]
 service-threads 4
 transaction-queues 4
 transaction-threads-per-queue 4
 transaction-max-ms 10000
 proto-fd-max 15000
}

```

info\_node\_info\_reduce\_fn(void \*key, void \*data, void \*udata) is written badly:

cf\_debug uses g\_service\_str without synchronization (string can be during cf\_free or strdup), also there is return(-1) without releasing mutex;

info\_get\_service is missing obvious pthread\_mutex\_lock(&g\_service\_lock) + pthread\_mutex\_unlock(&g\_service\_lock);

Your observation is correct. This has been fixed 😄
