[pgpool-general: 4597] Re: PGPoolII-3.5 : segfault during pcp_recovery

[Christophe Le Roux]

Hello,

Thank you for your answer.
Log files attached to my first message are already the debug output of each pgpool’s nodes, but as I’m not an expert of pgpool or watchdog I don’t know what is good and what is wrong.
Do you have the knowledge for reading and understanding them ?
I hope you do ☺

Regards,

Christophe

Hello.
You can try enable debug in pgpool.conf for obtaining more information.

Objet : [pgpool-general: 4569] PGPoolII-3.5 : segfault during pcp_recovery

Hello,

I am trying to setup 2 server (centos 6) with postgresql 9.5.1 (package from postgresql.org<http://postgresql.org>) and pgpool-II-3.5.0-1 (package from postgresql.org<http://postgresql.org>) in HA . You will find in attachement the config, debug output and /var/log/messages extract.

I have segfaults in /var/log/messages :
Mar 23 10:46:35 serv-ed01 kernel: pgpool[17611]: segfault at 8 ip 0000000000455517 sp 00007f995492db98 error 4 in pgpool[400000+133000]
Mar 23 10:47:12 serv-ed01 kernel: pgpool[17670]: segfault at 408 ip 000000000045551b sp 00007f9953d1eb48 error 4 in pgpool[400000+133000]
Mar 23 10:47:44 serv-ed01 kernel: pgpool[17723]: segfault at 8 ip 0000000000455517 sp 00007f995471fb98 error 4 in pgpool[400000+133000]
Mar 23 10:48:16 serv-ed01 kernel: pgpool[17788]: segfault at 8 ip 0000000000455517 sp 00007f9956522b98 error 4 in pgpool[400000+133000]
Mar 23 10:48:48 serv-ed01 kernel: pgpool[17828]: segfault at 1 ip 00007f9959f02e2c sp 00007f9955b21230 error 4 in libc-2.12.so<http://libc-2.12.so>[7f9959ebb000+18a000]


A detail wich can be important : AS the pgpool process is running with postgres user, “ip addr” and “arping” commandes are custom scripts with the command preceded by a sudo.


Could you help me to find what’s wrong ?


Regards,

Christophe
