Re: [ODBC] ODBC crash after DB cleanup

Hi,

 

We are using PostgreSQL release 9.3.14 and psqlODBC release 09.03.0400 configured over linux based OS. We are encountering an issue in production where we are observing ODBC crash after rehoming(cleanup of database) and BTS sites are going down after this activity. This issue is observed 3 times in production environment.

Below the bt of the core file.

 

(gdb) bt

#0  0x000000555a0323c0 in strcpy () from /srv/Log/bak/mnt/backup/iso/lib64/libc.so.6

#1  0x00000055c53ddfa4 in SC_create_errorinfo (self=Cannot access memory at address 0x55bbfe80e0

) at statement.c:1416

Cannot access memory at address 0x55bbfe8108

(gdb) disassemble SC_create_errorinfo

We are trying to reproduce the issue in local environment, no success yet. Enabling ODBC debug logs on production is not an option as we see 50% decrease in performance when we enable ODBC logs.

Please help us in resolving this issue.
