Problem Symptoms:
* "Cannot read reply" in GUI with this message in pc_server.log:
Empty table /tmp/utf_files/exlibris/aleph/u20_1/alephe/tab/tab_version

* Course Reading module is unavailable and error ?€žError parsing find request" when performing searches in XXX30-library

Cause:
Some Aleph processes were started by root user instead of aleph user.

Resolution:
1. Check if (apart from apache) any active Aleph process is still belonging to root user:

Example:
>ps -eaf | grep root | grep aleph
root 4129 1 0 Sep20 ? 00:00:13 /exlibris/aleph/a20_1/product/local/apache/bin/httpd -d /exlibris/aleph/u20_1/alephe/apache
root 11080 1 0 Oct03 ? 00:01:17 /exlibris/aleph/a20_1/aleph/exe/rts32 ue_11_a xxx00.a20_1

In this case ue_11 is belonging to root user.

2. As root user shutdown the Aleph processes belonging to root

3. As aleph user perform aleph_shutdown

4. Check if any files under utf_files-directory are belonging to root user:
> cd $aleph_utf
> pwd
/tmp
> find . -user root -print
./utf_files/exlibris/aleph/u20_1/xxx10/tab/tab_z105_filter
./utf_files/exlibris/aleph/u20_1/alephe/tab/tab_io_remote
./utf_files/exlibris/aleph/u20_1/xxx30
./utf_files/exlibris/aleph/u20_1/xxx30/tab
./utf_files/exlibris/aleph/u20_1/xxx30/tab/tab_publish

5. As root user delete all files and directories under /tmp/utf_files
6. Restart all Aleph processes as aleph user (aleph_startup)
