Hi!
First problem observed:
There may be a problem with a memory leak in Linux-2.1.49. This is the SMP version.
Conditions: No network daemons, only two getties, only the root file-system mounted (1.2gb, 91% full):
MemTotal: 46900 kB MemFree: 35532 kB MemShared: 6428 kB Buffers: 1796 kB Cached: 4448 kB SwapTotal: 100344 kB SwapFree: 100344 kB
I execute `ls -R /` then I have this memory available:
MemTotal: 46900 kB MemFree: 1016 kB MemShared: 6432 kB Buffers: 11732 kB Cached: 4600 kB SwapTotal: 100344 kB SwapFree: 100344 kB
I execute `ls -R /` again. Then I have this memory available:
MemTotal: 46900 kB MemFree: 768 kB MemShared: 6432 kB Buffers: 12228 kB Cached: 4608 kB SwapTotal: 100344 kB SwapFree: 100336 kB
I execute `ls -R /` again. Then I have this memory available:
MemTotal: 46900 kB MemFree: 468 kB MemShared: 6432 kB Buffers: 12348 kB Cached: 1724 kB SwapTotal: 100344 kB SwapFree: 100124 kB
Free memory goes down, swap usage goes up. If I execute this is a loop from a shell-script for about 3 hours, I can no longer fork and the shell fails.
Second problem observed:
Ftp between two linux machines, both running Linux 2.1.49. If I attempt to 'get' two files in a row, without waiting for several seconds, I get:
bind: Address already in use.
This might be caused by sockets remaining in their "CLOSING" state for a long time, i.e.:
Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (State) User tcp 1 1 chaos.analogic.co:smtp joshua.fuller.edu:1846 CLOSING root Active UNIX domain sockets Proto RefCnt Flags Type State Path
This mail from linux-kernel was received over an hour ago. It should not still be in the "CLOSING" state. It will eventually go away but after other states such as "TIME_WAIT", etc.
