### Description ### Troubleshooting By executing an external script using exec_cmd function I'm getting the following error: ``failed. exit_status=13, errno=11: Resource temporarily unavailable`` This is happening intermittently, sometimes it's working fine, but sometimes I see this error in the log file. After looking in the debug log file I found that for some reason the exit code for the executed command is not 0 (ki_exec_cmd(): execution return code: 1), that's why this function is complaining (I guess). What is weird that this is not happening permanently, it's about 2 cases from 5, and by running the same command manually - every time I'm getting success, all the time exit code is 0. (I'm running the same command with the same user like kamailio is running) Replacing exec_cmd with exec_avp - I didn't notice this issue. #### Debugging Data ``` 2376cc5b10f549@192.168.0.1:5060} exec [exec_mod.c:278]: ki_exec_cmd(): executing [nice -20 /usr/local/bin/cmd arg1 arg2 2376cc5b10f549@192.168.0.1:5060} dialog [dlg_hash.c:1069]: dlg_unref_helper(): unref dlg 0x7fd643b32398 with 1 -> 4 376cc5b10f549@192.168.0.1:5060} <script>: [From=sip:+123456789@company.net, To Domain=company.net, R-URI=sip:+987654321@192.168.0.1:5060] 2376cc5b10f549@192.168.0.1:5060} <core> [main.c:905]: sig_usr(): SIGCHLD received: we do not worry about grand-children 2376cc5b10f549@192.168.0.1:5060} exec [exec_mod.c:282]: ki_exec_cmd(): execution return code: 1 2376cc5b10f549@192.168.0.1:5060} <core> [core/action.c:1598]: run_actions(): alert - action [corefunc (16)] cfg [/etc/kamailio-dev/conf.d/routes.cfg:1567] took too long [780373 us] 2376cc5b10f549@192.168.0.1:5060} dialog [dlg_hash.c:877]: internal_get_dlg(): ref dlg 0x7fd643b32398 with 1 -> 5 ``` ### Possible Solutions Use exec_avp instead ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.4.1 (x86_64/linux) a6cb74 ``` * **Operating System**: ``` CentOS 7 x64 Linux k3-core1.nuacom.eqx 3.10.0-1127.8.2.el7.x86_64 #1 SMP Tue May 12 16:57:42 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
