I have experienced a sort of memory leak running a Warp with asterisk and gsm module: after some calls via GSM trunk, asterisk + freepbx stops working saying

WARNING[3066]: res_agi.c:313 launch_script: Failed to fork(): Cannot allocate memory

The Warp runs PADS, asterisk was upgraded following this link: http://forum.pikatechnologies.com/sh...terisk-version

This is the free output (Warp with 2 GSM trunk configured, no calls)
