Hi
all,
I have seen a weird
behavior of my DS (1.1.2). It has a very small database (only about 2300
objects). A client performed a one-level search retrieving the children. The
server find 114 objects, but the search was very slow:
[06/May/2010:12:23:11 +0000] conn=127 op=149 SRCH base=<base>
scope=1
filter="(&(&(objectClass=<xyz>)(<att1>=value))(!(<att2>=TRUE)))"
yes, the filter is a
bit complex, but both attribute types <att1> and <att2> are indexed.
This search usually is fast. It looks to me that the server is already in a
funny state.
...
[06/May/2010:12:23:17 +0000] conn=127 op=149 RESULT err=3 tag=101
nentries=114 etime=7
When the client gets
the results, it iterates over those and gets its children,
like:
[06/May/2010:12:23:17 +0000] conn=127 op=150 SRCH base=<dn of
result from previous SRCH> scope=1
filter="(&(&(objectClass=<uvw>)(<attr3>=*))(!(<attr2>=TRUE)))"
attrs=ALL.
Those searches are
quick:
[06/May/2010:12:23:17 +0000] conn=127 op=150 RESULT err=0 tag=101
nentries=1 etime=0
but somehow the
server does not process on of the requests, when the client iterates over the
results:
[06/May/2010:12:23:18 +0000] conn=127 op=263 SRCH base=<dn of
result from previous SRCH> scope=1
filter="(&(&(objectClass=<uvw>)(<attr3>=*))(!(<attr2>=TRUE)))"
attrs=ALL.
[06/May/2010:12:23:18 +0000] conn=127 op=263 RESULT err=0 tag=101 nentries=1 etime=0
[06/May/2010:12:23:26 +0000] conn=127 op=265 SRCH base=<dn of result from previous SRCH> scope=1 filter="(&(&(objectClass=<uvw>)(<attr3>=*))(!(<attr2>=TRUE)))" attrs=ALL.
[06/May/2010:12:23:18 +0000] conn=127 op=263 RESULT err=0 tag=101 nentries=1 etime=0
[06/May/2010:12:23:26 +0000] conn=127 op=265 SRCH base=<dn of result from previous SRCH> scope=1 filter="(&(&(objectClass=<uvw>)(<attr3>=*))(!(<attr2>=TRUE)))" attrs=ALL.
[06/May/2010:12:23:26 +0000] conn=127 op=265 RESULT err=0 tag=101
nentries=0 etime=0
You can see that the
server skipped op=264. It looks to me that the request came in, but somehow the
server joked up, before it could log the request in access.
Has anybody seen
such a behavior before?
Thanks,
