The scripts in the bug report were using mysqli i don't know if it's relevant, but there was recently a fixed bug wrt snmp memory leakage: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=423296 this is the debian bug report, but it has links to php.net and gentoo bug reports. it also has a patch in the report that you can directly take. the fixed debian version is 5.2.6-4, so i would expect any ubuntu package of greater version to also contain the fix, since they sync from the debian packages. sean
