General error: 2006 MySQL server has gone away.

[joy11]

I'm running 5.0.5 now, but was previously running 5.0.3 as of this morning. I have an error that has started to show up about a week ago for 2 email accounts. This example is from a power user of the system and approximately every 2 hours this same message is showing up in my error logs 20 times in a row then has the PDOException error and then 20 more of the email and the PDOException again. This user hasn't really complained about performance issues yet.

[2018-02-19 19:06:27] Espo.ERROR: EmailAccount 58aef598dd3172de5 (Import Message w/ MailMimeParser): [HY000] SQLSTATE[HY000]: General error: 2006 MySQL server has gone away []

followed by this:

[]
[2018-02-19 19:06:27] Espo.ERROR: Uncaught Exception PDOException: "SQLSTATE[HY000]: General error: 2006 MySQL server has gone away" at /home/servername/public_html/application/Espo/ORM/DB/Mapper.php line 768 {"exception":"[object] (PDOException(code: HY000): SQLSTATE[HY000]: General error: 2006 MySQL server has gone away at /home/servername/public_html/application/Espo/ORM/DB/Mapper.php:768)"} []


I looked up the first SQLSTATE error and it appears possibly related to timeouts.

Any ideas what could be going on?
