Hi all,
If I start two o more connections with diferent users that make a search text to solr I get this message many times:
Error: fts_solr: Query didn't return uid
If I repeat the test about 2000 times, with only one user concurrent, with 60 diferent users, without concurrent, I get between 0.
If I repeat the test about 2000 times, with 2 users concurrent, I get between 3 or 10 errors.
If I repeat the test about 2000 times, with 4 users concurrent, I get between 10-20 errors.
After see this error, I set a tcpdump to try to watch the SOLR XML and GET, I can watch that Solr send a xml like this:
<response></response>
with 200 as http status
When the normal response is like this
<response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">1</int> <lst name="params"> <str name="fl">uid,score</str> <str name="sort">uid asc</str> <str name="q">BLABLABLA</str> <str name="fq">+user:"ANYUSER" +uidv:1208469916 +box:"ANYFOLDER" -ns:[* TO *]</str> <str name="rows">1</str> </lst> </lst> <result name="response" numFound="0" start="0" maxScore="0.0"/> </response>
At first, I think that the problems it's in Solr, but after get all GET from tcpdump, I make a python script with urllib2 and send it all to Solr with the same concurrency and I can't get any error or "empty response"
Have someone made a intensive concurrency tests over Dovecot + Solr ?
