Hi all, I have koha running on a shared hosted server for a small private library. For the last couple of months, we've been getting an error off and on as below. The application has been running fine on the same service provider for the last two years, but the problem surfaced a couple of months back and the frequency of the problem has been increasing. Can't create a new thread (errno 35). If you are not out of available memory, you can consult the manual for a possible OS-dependent bug at /usr431/home/r/e/readersl/public_html/modules/C4/Context.pm line 411 Can't call method "prepare" on an undefined value at /usr431/home/r/e/readersl/public_html/modules/C4/Circulation/Fines.pm line 78. I would like to know if any of you have seen this issue on your installations. My guess is this is a MYSQL/ OS environment specific issue, but could you please provide any leads on how I can pursue this with my service provider? Could there be a mysql code optimization issue? Should we be doing any database maintenance? This question may seem like a database maintenance specific question, but any help/pointers will be appreciated. Thanks, Venita.
