[asterisk-users] Errors in console for zap

[Jon Weisman]

Hello,

Today I saw about 40 calls drop on my asterisk box. Its doing Zap to SIP w/ 
g729 compression. Wasnt sure what the problem is and now I'm monitoring the 
console and I see these strange errors. I'm running Asterisk 1.2.24

ALSO SEEING THESE:

These errors only appear when I'm going over 30 channels, but I never had 
these issues before. Any ideas?

Thanks in Advance,
