Hi All,
On SuSe Linux blade with 6GB of RAM.
with disk_access_mode mmap_index_only and mmap I see OOM map failed error
on SSTableBatchOpen thread. cat /proc/<pid>/maps shows a peak of 53521
right before it dies. vm.max_map_count = 1966080 and /proc/<pid>/limits
shows unlimited locked memory.
with disk_access_mode standard, the node does start up but I see the
repeated error:
ERROR [CompactionExecutor:6] 2012-06-06 20:24:19,772
AbstractCassandraDaemon.java (line 134) Exception in thread
Thread[CompactionExecutor:6,1,main]

...
I'm not sure the second error is related to the first. I prefer to run with
full mmap but I have run out of ideas. Is there anything else I can do to
debug this?
Here's startup settings from debug log:
