[tg] Possible mem leak?

[Rafter, Marcel]

Hello all,
I am using TG on three servers, two FreeBSD and one Linux server. TG is configure to send and receive a number of TCP protocols between the three servers to simulate a real network. The Linux server is doing the most work running 8 TCP sinks and sending 16 TCP sources. The sources are set to run every twelve hours using cron while the sinks run all the time. The problem is after a couple of days the Linux server runs out of memory and freezes. It has to be rebooted to make the server useable again. The TG program has been moved from one Linux server to another so I do not think the problem is hardware. I started using the Linux binaries but then I compiled the source code to see if that solved the problem, but no. Below is output from syslog. I have had no problems on the FreeBSD servers. Can you please help? What can I try?

thanks,
Marcel
