System malloc out of memory

Hi, my ISPconfig works perfect. But i got strange error yesterday. It seems like:

I tried fix it into dovecot.conf, as google advised. But it didnt help. It is someting easy, but i dont understood. Thanks for help

 

It may be dovecot.conf does not help here.
If your computer runs out of memory, you can

• add swap file or swap partition
• install more RAM memory to the computer
• try to configure applications to use less memory, but this may turn out to be difficult
• monitor the system to see what is using the RAM, to maybe configure that application

If your computer is running on some cloud service it may be easy to add memory, and then restart the host.

 

Try to increase your vsz_limit in dovecot.conf:

Code:

service imap {
  vsz_limit = 512M
}
