Re: replicator: Panic: data stack: Out of memory when allocating ...

[Joelly Alexander]

Same issue since Debian 8 (actually running Debian 10) and tried everything what was mentioned but found nothing that fixed it, doesn't seem to be Debian related as other users reporting the same problem on Arch or CentOS without being able to fix.

I've seen thread with problem identical to mine started "Fri May 28 13:54:27 EEST 2021" and I was wondering did you get to fix this issue? And setting vsz_limit = 0 doesn't help either - it just tries to allocate all available memory.
