Hi,

I'm running standard 2.4.22 kernel, 2xP4 Xeon with 2Gb RAM.

After reaching 127 filesystems on the server, all formatted as reiserfs, 
I now find the following errors are occurring:


reiserfs: found format "3.6" with standard journal
reiserfs: using ordered data mode
loop(7,124):clm-2000, unable to allocate bitmaps for journal lists

Unfortunately I cannot decode the OOPS because kernel symbols don't 
appear to be exported on kernels with no loadable module support.

I also start to see errors like:

$ iptables -F
iptables: Memory allocation problem

I was hoping to mount 254 filesystems on this server.  Another server 
running ext2 successfully runs with over 1000 filesystems and another 
with ext3 runs 220 filesystems.

This is 100% reproducable. Is there anything I can do about this ?


Regards,


Nick.
