Subject Help understand a couple of error messages
Author Douglas Tosi

I would like to understand a couple of messages that appear in firebird.log:

This is Firebird 2.1.1 CS on Debian 2.6.25.

1) "page 0, page type 1 lock conversion denied (215)"
This error is apparently related to:

What does it mean? What causes it?
It seems related to the header page (page 0). Is it serious (corrupts data)?

2) "Number of requested semaphores (64) is greater then size of the
existing semaphore set (32)"
Appeared after increasing LockSemCount from 32 to 64.
Google was not very helpful here.
What can be preventing the increase to the semaphore set?

Thank you,
Douglas Tosi
