Hi all
I am building an extension using shared memory hash table and for locking
hash table i am using LWLocks, but the thing was when i try to run some 1k
queries one after other, for each query i am getting one LWLock but on
executing 200th query i am getting the error *ERROR: too many LWLocks
taken*.
But in each query i acquire and release that block. So that lock has to be
flushed after executing query, but why am i getting this error.?
Is this due to *held_lwlocks *in LWLock.c is fixed only to some number 200
here.
Or am i missing something here.?
thanks
harry
