rmap overflow errors in quadrant 4

I have been experiencing errors in the syslog that have to do with mmap. The error is: vmunix: quad4map_32bit: rmap ovflo, lost [982699,982721].

We we're experiencing problems when applications are loading libraries (i.e. Can't mmap()). Our resolution was to enable quadrants 3 and 4 via chatr (i.e. chatr +q4p enable appName). This fixed our dlopen/can't load library problems but we are now seeing the rmap ovflow in the syslog.

Our kernel parameters are as follows:
maxdsiz=400000000
maxssiz=33554432
maxtsiz=256000000
shmmax=1073741824
shmmni=1024

If anyone can point me to some docs which describe these issues in detail, it would be much appreciated.

Thanks,
Chris Thompson
