Additional info: in the meantime, I've tried adding require_auth=3Dnone
and gssencmode=3Ddisable connection string parameters (separately, not
together at once) for the repmgr/client connections that are "trusted"
through pg_hba.conf, but the problem persisted.

Hi, <br>
<br>
I am intermittently getting following errors (taken from var/log/syslog), o=
n<br>
pg_basebackup, repmgrd and psql (so far) <br>
<br>
<br>
repmgr[1147164] general protection fault ip:7fb9950981b5 sp:7ffecf4418f8<br=

error:0 in libkrb5.so.3.3[7fb99506a000+5f000]<br>
also this:<br>
<br>
pg_basebackup[4191295] general protection fault ip:7f344e9771b5<br>
sp:7ffe8c625c28 error:0 in libkrb5.so.3.3[7f344e949000+5f000]<br>
<br>
and this<br>
<br>
psql[4045720] general protection fault ip:7f89130931b5 sp:7fffd40a0268<br>
error:0 in libkrb5.so.3.3[7f8913065000+5f000]<br>
<br>
Looks like that the error is related to GSSAPI/kerberos auth? I have tried<=
br>
replacing &quot;host&quot; type within pg_hba.conf to &quot;hostnogssenc&qu=
ot;, but problem<br>
persists. <br>
<br>
Running Debian 12 with all updates, repmgr, timescaledb extensions (fresh<b=
r>
install). PostgreSQL 16.1 (Debian 16.1-1.pgdg120+1)<br>
Looks like the server itself is not affected (isn&#39;t crashing etc). <br>
<br>
Is there anything that I could do to disable GSSAPI/kerberos and/or<br>
circumvent this issue? Also, how can I provide more info for this issue to<=
br>
be resolved.=C2=A0 <br>
<br>
Thanks.<br>
