[asterisk-users] Defunct / zombie AGI after some execution time
Hello, We are running Asterisk-1.0.12 in a CentOS 4-4.2 system, kernel 2.6.9-42.0.3.ELsmp. We have some custom AGI, and when we launch Asterisk the system works fine. But **after some time**, each AGI execution generates a zombie <defunct> process. We believe that it's not a problem in the AGI code, because Asterisk+AGI is working fine in the first "n" minutes/hours. This is a pstree sample: init-+-asterisk---asterisk---48*[asterisk] But after some execution time, this is the pstree output: init-+-asterisk---asterisk-+-28*[asterisk] | |-asterisk-+-21*[xxxxxxxxx.agi] | | `-40*[xxxxxxxxx.agi] | |-5*[asterisk-+-yyyyyyyyy.agi] | | |-zzzzzzzzz.agi] (...) Each agi is a defunct process. It dies when the call (parent) finishes. When the first zombie appears, then ALL next AGI launched from Asterisk generates a zombie. We have tested some improvements to solve the problem, with no success: - Upgrade from RedHat 8 to Centos 3.x - Upgrade from Centos 3.x to Centos 4.x - LD_ASSUME_KERNEL=2.4.1 - ulimit -n 65535 - Upgrade from asterisk 1.0.7 to 1.0.12 Currenly we can not easily migrate from asterisk-1.0.x to 1.2.x Any ideas?. Could be Debian a solution? Thank you.
