[sr-dev] [kamailio] Kamailio crashes if i use $expires(max) (#495)

3 Feb 2016


      Hi there
After modifying my kamailiocfg script, I started getting crashes on the first message I tried to process I've traced the crash to the following line in the script:
```
if($expires(max)==$null) {
```
This is the log I get: (I've tried setting the debug level to 4, but there's no extra information)
```
Feb  3 15:09:35 machine /usr/sbin/kamailio[15802]: CRITICAL: <core> [pass_fdc:275]: receive_fd(): EOF on 19

```
The message I'm trying to process is (sensitive info removed):
