anyone using linux ops cluster as production database?

We have a suse7/oracle 81701 database cluster, and it seems not quite stable. After one week or two, one of the ops instance will down, and made the whole node reboot. Most of the time, it is the lmon process that made the oracle down, thus the node down. I suspect whether my ops instance parameter is ok:

lm_locks integer 67414 lm_ress integer 66487 The two node has 2 cpu and 1 g memory each. Can someone here using the linux ops post your configuration parameter? Thanks. alert log: Thread 1 advanced to log sequence 153 Current log# 3 seq# 153 mem# 0: /dev/raw13 Fri May 17 02:44:18 2002 LMON: terminating instance due to error 29702 Instance terminated by LMON, pid = 573
