Icinga Version: 1.10.0
OS Version: any

just an informational note, when working on old RHEL boxes, where the native libdbd-pgsql binaries link against the old system native libpq 8.1 postgresql lib api, but the libpq installed is 8.4 targetting a postgresql server 8.4 on a 64bit system.

this leaks heavily memory, the root cause is dbd_ping, like the attached valgrind log shows. this has been run for ~12hours, assigning ~600m memory to the ido2db process.

presumingly this is fixed in all other upstream versions (debian 6, libdbi 0.8.2-2, libpq 8.4).

some bug reports from 2006;a=log;h=42c65bf8476bdd58713abf1c72004b903d7dc223

i guess the rhel5 libdbi version is just broken and should be replaced by a proper packaging - i.e. shipped via repoforge 3rd party repo.
