The stack is definitely leaking sockets. I can now reliably reproduce the problem by opening a TCP connection and then immediately causing a TCP reset. I've got 9 open sockets to start with, and max sockets is configured to be 256. After repeating the open/reset sequence 244 times, I get an "DEBUG: Out of sockets - waiting" message that repeats periodically (but never recovers). At that point, I can still ping the eCos system, but no new connections can be opened. In case anybody else would like to try it, here's a win32 program that opens/resets a tcp connection 4 times per second: http://www.panix.com/~grante/files/ecos/winopenclose.c http://www.panix.com/~grante/files/ecos/winopenclose.exe The accept() call will return -1 with errno==353 when the socket is leaked. -- Grant Edwards grant.b.edwards Yow! ... the MYSTERIANS are at in here with my CORDUROY gmail.com SOAP DISH!! -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
