Here is the output:
http://hosting.telecoms.bg/~moskov/gdb-mono_backtrace_15.txt.gz

We made some tests and here is an test app that seems to reproduce our problem:
http://hosting.telecoms.bg/~moskov/WebTest.tar.gz

It has 10 user control which are loaded dynamicly after clicking one
of 10 buttons. Every user control contains a data grid with 10000
rows. On my test machine which  has 256Mb RAM the problem shows after
loading the third user control, and top looks like this:

Mem:    255756k total,   248120k used,     7636k free,     3544k buffers
Swap:    72252k total,     5616k used,    66636k free,    24212k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
