Luigi Posted August 30, 2022 Share Posted August 30, 2022 Hello, I have a lot of problem with this exception: Exception: Unable to obtain lock for session (retry in 30s) (in wire/modules/Session/SessionHandlerDB/SessionHandlerDB.module line 96) #0 [internal function]: SessionHandlerDB->read('69f8229e5ff1e62...') #1 wire/core/Session.php (319): session_start(Array) #2 wire/core/Wire.php (414): Session->___init() #3 wire/core/WireHooks.php (951): Wire->_callMethod('___init', Array) #4 wire/core/Wire.php (485): WireHooks->runHooks(Object(Session), 'init', Array) #5 wire/core/Session.php (201): Wire->__call('init', Array) #6 wire/core/ProcessWire.php (577): Session->__construct(Object(ProcessWire)) #7 wire/core/ProcessWire.php (313): ProcessWire->load(Object(Config)) #8 index.php (52): ProcessWire->__construct(Object(Config)) #9 {main} I installed local versions of my site on my computer and inside some docker container. I tried it with mariadb and mysql. The exception comes almost always at the first start of the website after I started my computer but it also appears a lot through the day. the pages are really slow when the exception does not appear. Another page of mine, a shopware instance, runs quite faster in comparison to the processwire page and I don't have the problem with this exception on my regular server. Has anyone an idea what the problem could be? thanks a lot. Link to comment Share on other sites More sharing options...
nbcommunication Posted August 30, 2022 Share Posted August 30, 2022 Hi @Luigi, This is something that happens to some of our websites, some more info here: I've never been able to solve the issue, although as it is infrequent and has always passed before I notice the email error notifications, I've never really spent a lot of time trying to replicate and debug it. In the linked thread it was said that disabling Tracy Debugger worked - I don't have this on the sites where this error tends to happen, but if you do perhaps that will solve it. Cheers, Chris 2 Link to comment Share on other sites More sharing options...
Luigi Posted August 30, 2022 Author Share Posted August 30, 2022 @nbcommunicationthanks a lot for your answer. Disabling tracy reduced the error but it still appears some times. Link to comment Share on other sites More sharing options...
