Insufficient allocations in net/unix/garbage.c
...kernel removed from To: list. --alex]
-----BEGIN PGP SIGNED MESSAGE-----
Kernels 2.0.x do not sufficiently allocate space for the internal stack
used for garbage collection on unix domain sockets. I have neither
examined nor tested 2.1.x kernels.
Because the garbage collection system defines a MAX_STACK depth of 1000
for it''s internal use, it is relatively trivial to write a user-space
program which opens up a large number of unix domain sockets, eventually
causing a kernel panic in the garbage collection routines (which test for
this limit and panic if hit); on systems which have NR_FILE...

Solution to problem : dynamic variable drops with non-empty dirty list
...osts suggested, but I am still having a problem with my dtrace application running on a heavily loaded system. I have the following lines in my D script,
#pragma D option aggsize=8m
#pragma D option bufsize=16m
#pragma D option dynvarsize=16m
#pragma D option aggrate=0
#pragma D option stackframes=MAX_STACK
#pragma D option cleanrate=50Hz
but still I am getting the following messages,
Drop: 17458 dynamic variable drops
Drop: 3426 dynamic variable drops with non-empty dirty list
and the amount data that my D script is reporting, is gradually dropping.
This means that the tuning that I am...
