At present, I provide my maintenance experience over the past few years and some of my private solutions.

The first possibility:

Remove the eaccelerator extension in php
This can solve your problem, but it may increase the burden on the system.
Because eaccelerator is mainly used to save system resources

The specific method is to find php. ini
If it is configured for you, usually in c:/php. ini, c:/winnt/php. ini, or c:/windows/php. ini

Remove

Zend_extension_ts = "C: \ php \ extensions \ eaccelerator_win_xxx.dll"
Eaccelerator. shm_size = "16"
Eaccelerator. cache_dir = "c: \ temp"
Eaccelerator. enable = "1"
Eaccelerator. optimizer = "1"
Eaccelerator. check_mtime = "1"
Eaccelerator. debug = "0"
Eaccelerator. filter = ""
Eaccelerator. shm_max = "0"
Eaccelerator. shm_ttl = "0"
Eaccelerator. shm_prune_period = "0"
Eaccelerator. shm_only = "0"
Eaccelerator. compress = "1"
Eaccelerator. compress_level = "9"

Ea is mainly developed in unix environment, but the author ignores that windows is not actually the same as u host, and there is no memory sharing mechanism of u host.
This bug has been submitted to them, and we hope 0.9.5 can solve it.

Of course, if this problem is not serious on your machine, we recommend that you retain it. ea is a very good Php Cache + acceleration software.
Combined with zo, the system load will be reduced by about 50%-80%, and the load capacity, speed and efficiency will be improved by about 200%.

 

Second possibility

Session_save_path needs to set an actual physical path, and this directory requires all the permissions of everyone, similar to the 0777

 

Third possibility
C:/winnt/temp or c:/windows/temp
You also need all the permissions of everyone, similar to 0777 of the U host.

 

Fourth possibility
Your memory is seriously insufficient. check whether there is any problem. please add the memory. it is best to add two at a time.
For example, to add 1 GB memory, it is best to add 2 identical 512 MB. Otherwise, the dual-channel is not enabled, and the effect is normal.

 

Fifth possibility
ZendOptimizer does not work well with php
Try another version
Currently, the stable combination is:
Php4.3.11 + zo 2.5.10a
Or php4.4.1 + zo 3.0 beta2

 

Sixth possibility

Most of these are win2003 users.
They set limits in the application pool.
For example, how long is it to be recycled and how much memory is used?
These settings will inevitably cause this classic php error
After hundreds of tests on wood, the problem can be guaranteed.
