>Environment:
2.2 from mid-february, being used as a router with 16M of memory, gated.
Usually either max 16 pppds and couple of rlogins and gated, couple of
small programs for accounting, nothing else. Hardware is cyclades + basic
IDE + 486-66 to pentium-133 configuration (8 of them, various different
motherboards and cpus).
There are routing changes all the time. Other possible points of leak are
in kernel ppp (pppd). I cannot figure out what else could be causing this.
>Description:
2.2 seems to leak memory somewhere. These systems become slow and vmstat
shows wild swapping for no obvious reason. The system seems to be
extremely slow, looses characters on input and gettys seem to get the line
speed wrong (thats weird as they are supposed to be locked to 115.2k and
getty should not try anything else but 115.2k!). Reboot cures the problem
for some time. I do not know if this could be lack of memory; it seems
odd, as the programs being run are small and they do not show any growth
related to load increase.

I cannot say exactly when this started but I think I have noticed it during
1997, but not fall 1996.
