I've been fighting something that sounds at least similar -
at particular customer sites - for over a month. For me, it's locking
up about every 48-60 hours, with a casually polling Modbus
TCP connection (~ 200 ms between polls) - and lwIP 1.2.0. It
requires a power cycle of our equipment to restore the operation of the stack.
I have had this reported in only two locations out of
many however... and have not been able to duplicate it in the
lab. From: address@hidden [mailto:address@hidden On Behalf Of Taranowski, Thomas (SWCOE) Sent: Wednesday, February 27, 2008 5:31 PM To: Mailing list for lwIP users Subject: [lwip-users] Problem with long term running of lwIP. I have an application in which is
receiving and sending UDP traffic over a long-term period. After about 6
hours, something flakes out. I was hoping I could get some input on
possible causes. Any ideas here on what the problem could be? Is
anyone else having a similar problem? Other
data: I’m sending and receiving 50
packets/s over the period of 6 hours, at a fairly steady rate. (~1,000,000
packets) Some packets are fragmented, others
are only about 100 bytes. The
symptoms: Somewhat
random Sometimes ping stops working, other
times it still works. Sometimes one UDP port stops
working, other times all of them cease to function. I’m running a cvs head from around
Dec 3. At the time, the head was stable and looked pretty
solid. |
