Sockets can go stale especially on windows Op systems. Arrange you programs to break connections and reestablish connections every few hours and see if that helps

I am running a TS-7260 with lenny user space, a 2.6.21-ts kernel, and a TS-GSM1 expansion card. I am streaming data across the cellular modem link using ssh port forwarding. I notice that after a day or so of testing, I will often observe unusual behavior with the board that goes away after rebooting. For example,

(1) In one case, after terminating the test, I attempted to ping the remote IP address and received this message "ping: sendmsg: No buffer space available". Odd.
(2) In another case, after the board had been up for a day, I attempted to look at some of the pppd configuration files. Although the files were visible with an 'ls', if I attempted to 'more' them, I would be told that the files did not exist.
(3) After streaming data for 4 days over the ethernet connection (instead of the TS-GSM1), I noticed an error message in the console window: "ERROR: (device tssdcarda4): DT_GETPAGE: dtree page corrupt." When I attempted to move files around, I was told that the file system was read only. After rebooting, things functioned normally.
(4) After running for about a day, I attempted to run g++ and it seg faulted. I attempted to run apt-get to reinstall g++, and it returned with undefined symbol errors. After rebooting, things functioned normally.

I'm wondering if anyone else has experienced problems like these, and if anyone has any ideas of what could be causing them. I thought that maybe there is a memory leak somewhere, but I don't know how I would even check for that. Any assistance is appreciated.
