Bug reference: 3999
Logged by: Thomas Poindessous
Email address: t(dot)poindessous(at)seiitra(dot)com
PostgreSQL version: 7.4.9
Operating system: RHEL 3ES.x86_64
Description: Panic with "invalid string enlargement request size"
after a strange request from JDBC
we have some PANIC after a weird error :
ERROR: invalid string enlargement request size 1358954492
WARNING: AbortTransaction and not in in-progress state
ERROR: could not send data to client: Broken pipe
PANIC: error during error recovery, giving up
Postgresql server restarts well.
We traced the connection and it comes from a jdbc application. We use
Here is a excerpt from the tcpdump log (only incoming cnx) :
000000BA 51 00 00 00 24 73 65 74 20 63 6c 69 65 6e 74 5f Q...$set
000000CA 65 6e 63 6f 64 69 6e 67 20 3d 20 27 55 4e 49 43 encoding =
000000DA 4f 44 45 27 00 ODE'.
000000DF 58 51 00 00 00 04 XQ....
We noticed than the 58 51 couple of bytes is unusual.
We know that we have a very old version of 7.4, we will migrating to 8.3
RSN, but we would like to know if it's a known bug of the jdbc connector for
example, or if we have a problem with our application's code.
Thanks in advance.
