Looks like some sql related problem but I cant replicate it as I have no clue whats going on. Everything worked fine until beginning of august.

I use one huge plugin which use the old dbi module but it havent been any problems with it before.

[Lt Llama]

This is probably and an old problem I had with dbi_nextrow() for the old dbi I forgot I misuse. Forgot to move the tweaks over to a newer version of my sql plugin. Fixed it and I will check if I get any more problems.

Originally Posted by BAILOPAN FYI: I found why this plugin was crashing. You're mishandling dbi_nextrow(). dbi_nextrow() returns 0 when there are no more results. In a few places in this plugin (around 976) you make while loops eating up results, and then call dbi_result() on the query. But by the time you get to dbi_result(), the result set will be entirely gone, as dbi_nextrow() will have finished looping them all. So, recheck your code for dbi_nextrow() usage. If you know the last call returned 0, you should not be checking any more rows or trying to get results. Furthermore, you should never call dbi_nextrow() without checking the result.

Solution: Delete everything + make a new server = Problem gone.
