Sounds like webcahe isn't happy about something.

Messages are not necessarily a problem. If you take the following survey:

1) Is the application fully functional?

2) Is the entire application working on one server or are multiple servers involved?

3) Are there any messages in the httpd logs or the webcache log?

If the answer to 1 is yes, please consider doing nothing.

If the answer to 2 yes yes, consider uninstalling webcache because you don't need it on a single server installation.

If the answer to 3 is no, once again consider doing nothing.

We have substantial expereince with this application.

It is not "webcached" that is complaining, it is the system.

$ man 2 wait

ECHILD if the process specified in pid does not exist or is not a child of the calling process. (This can happen for oneâ s own child if the action for SIGCHLD is set to SIG_IGN.

See also the LINUX NOTES section about threads.)

$ man signal

According to POSIX (3.3.1.3) it is unspecified what happens when
SIGCHLD is set to SIG_IGN. Here the BSD and SYSV behaviours differ,
causing BSD software that sets the action for SIGCHLD to SIG_IGN to
fail on Linu
