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

[Sebastian Podjasek]

I've seen thread with problem identical to mine started "Fri May 28

Mine looks like this:

dovecot: replicator: Panic: data stack: Out of memory when allocating 1073741864 bytes
dovecot: replicator: Error: Raw backtrace: /usr/lib/dovecot/libdovecot.so.0(backtrace_append+0x42) [0x7f57c5a4c4e2] -> /usr/lib/dovecot/libdovecot.so.0(backtrace_get+0x1e) [0x7f57c5a4c5fe] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc49b) [0x7f57c5a5849b] -> /usr/lib/dovecot/libdovecot.so.0(+0xfc531) [0x7f57c5a58531] -> /usr/lib/dovecot/libdovecot.so.0(+0x53aee) [0x7f57c59afaee] -> /usr/lib/dovecot/libdovecot.so.0(+0x53435) [0x7f57c59af435] -> /usr/lib/dovecot/libdovecot.so.0(+0xf5d88) [0x7f57c5a51d88] -> /usr/lib/dovecot/libdovecot.so.0(+0x11b818) [0x7f57c5a77818] -> /usr/lib/dovecot/libdovecot.so.0(+0xf25f2) [0x7f57c5a4e5f2] -> /usr/lib/dovecot/libdovecot.so.0(+0xf26a9) [0x7f57c5a4e6a9] -> /usr/lib/dovecot/libdovecot.so.0(buffer_write+0x1e) [0x7f57c5a4e8be] -> dovecot/replicator(replicator_queue_push+0x14a) [0x55aabc673b1a] -> dovecot/replicator(+0x5296) [0x55aabc673296] -> dovecot/replicator(+0x493e) [0x55aabc67293e] -> dovecot/replicator(+0x4acc) [0x55aabc672acc] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_call_io+0x69) [0x7f57c5a6df59] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run_internal+0x132) [0x7f57c5a6f592] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_handler_run+0x50) [0x7f57c5a6e000] -> /usr/lib/dovecot/libdovecot.so.0(io_loop_run+0x40) [0x7f57c5a6e1c0] -> /usr/lib/dovecot/libdovecot.so.0(master_service_run+0x13) [0x7f57c59e44e3] -> dovecot/replicator(main+0x18d) [0x55aabc671cad] -> /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xea) [0x7f57c57b4d0a] -> dovecot/replicator(_start+0x2a) [0x55aabc671d6a]

And setting vsz_limit = 0 doesn't help either - it just tries to
allocate all available memory.

I'm running:

# 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.13 (cdd19fe3)
# OS: Linux 5.10.0-8-amd64 x86_64 Debian 11.0
