Could not write to log file

Deleting log files may cause a loss of important data. I would rather like to understand the cause of this, not the symptom.

I suppose that either your var/log/ directory or the file inside there was missing write permissions? Then the suggestion would need to be to adjust write permissions for the TYPO3 webserver user/process.

Or was your disk full? In that case the recommendaton would be to ensure enough diskspace, or to utilize logfile rotation.

@garvinhicking good point, added some more steps that could be checked

I could repeat now this issue. So I attach the debug output here.
It happens when I have kept a TYPO3 backend session open for a very long time. Now the relogin box appears. After I type my password and press the button, I come into this exception.

Here is the answer:

user:/homepath/typo3temp/var/log$ ls -ltr
total 4384
-rw-rw-r-- 1 dcp307300028 dcp307300028    1142 Jun 26  2024 tcpdfbill_tt_products.log
-rw-rw-r-- 1 dcp307300028 dcp307300028 2854912 Dec 28 20:31 typo3_deprecations_4b4937a2ac.log
-rw-rw-r-- 1 dcp307300028 dcp307300028 1622016 Dec 28 20:31 typo3_4b4937a2ac.log
user:/homepath/typo3temp/var/log$ 

So the log file still can be written despite of this exception.

If I repeat a click in the backend, then the time of the log files gets to the current time. However the file size does not increase.

Now I have done this:

chmod -R 777 typo3temp

Hm, it still shows the exception which blocks the TYPO3 backend.

Now I have checked the server tool.
