    external Server error 500


    Lock Manager error: '[LockManagerException] Can't open or create shared memory by shm.name: "GlobalSharedLockManagerStorage_v2"; shm.start_size: "4194304"; error "The paging file is too small for this operation to complete."'.


    ERROR: Out of memory (allocated 2097152) (tried to allocate 655360 bytes) (common_messages_en-US.php:7)

  • Application pools may be stopped in IIS.

  • The following error message appears in %plesk_dir%adminlogsphp_error.log:

    PHP Warning: PHP Startup: Unable to load dynamic library 'C:Program Files (x86)Pleskadminenginephp_plesk_util.dll' - The paging file is too small for this operation to complete in Unknown on line 0

Resolution

Adjust the server configuration in one of the following ways:

  • Allocate more RAM to the server
  • Increase Virtual Memory size
  • Kill some non-critical processes to free memory
  • If this is a temporary RAM increase, wait for a while for the high RAM load to reduce

Warning: This is an administrative task and has to be performed by a server administrator.
