Hi, I am currently evaluating ES as an alternative to SolR. My test environment consists of 4 m1.xlarge instances cluster on EC2, 8GB (out of 16GB) is allocated for ES JVM. The index is broken into 5 shards with 1 replica. For indexing JSON docs I'm using "Pyes" with "Bulking" enabled (chunks of 100 docs). I've encountered a problem when indexing about ~1.5 million of docs (same index) where I get time-out from ES and unable to index any new documents . The system load is normal, no swapping accrued, I also I couldn't find anything relevant in ES logs. Has anyone faced similar problem? -- Regards, Paul \*\* ---

What params did you use when you called ES() for a connection? e.g. from pyes import ES connection=ES([index\_server], bulk\_size=BS, timeout=TS) By default BS=400 and TS=5 (secs) Try adjusting the timeout value. timeout=None will not time out. ---
