Peculiar PHP Error

[background]

Hello,

recently, I get frequent errors in PHP log:

PHP Fatal error: Uncaught Exception: Serialization of 'CurlHandle' is not allowed in [no active file]:0

Since there is no file (how is this even possible?) I cannot find the source of the error.
Correlating the timestamps with Apache access log does not reveal a pattern.

Any suggestions what the cause can be?
Or please recommend me steps for tracking this down.

Thanks.
Thomas

Hello,

I'm encountering the same issue with frequent errors in my PHP log showing:
PHP Fatal error: Uncaught Exception: Serialization of 'CurlHandle' is not allowed in [no active file]:0

It's baffling since there's no active file mentioned, making it difficult to pinpoint the exact source of the error. I've tried correlating timestamps with the Apache access log, but haven't found any discernible pattern either.

If anyone has suggestions on what might be causing this or can recommend steps for tracking it down, I would greatly appreciate the assistance.
