Hi I'm having a problem that looks like Kannel's SMS box HTTP listener is locking up.
I've been running some load tests on Kannel, sending out 30K messages over a short space of time. I am running Kannel version 1.5.0 under Windows using Cygwin. I have no problem if it is running on my Windows 7 laptop, 32 bit 2.68G RAM, 2.53GHz. However, when it is running on one of our servers it locks up after about 24K messages. The server is Windows Server 2003 R2 Enterprise x64 Edition SP2, 2GHz with 8G RAM. The only difference between the two is the Kannel configuration file which points the log files to different places in the file system. Both instances of Kannel were compiled from the same source code on the target machines using the latest version of Cygwin. The server isn't under a heavy load. It is also running IIS. After Kannel locks up there are no further entries added to its log files and from what I've found the only solution is to stop and restart it. There doesn't appear to be anything additional logged from the server that isn't logged from my laptop. Has anyone else seen anything like this before? Any clues to what may be the cause or possible solutions would be greatly appreciated. I can post logs and config file if needed. Many thanks. -- Richard Crawshaw Software Developer
