MetaFrame(Client_Drive_Mapping)[809]: [ID 784276 user.error] 6601295: CTX1020E CDM failed to handle session reconnect for session 17 (error code Too many open files).

"Too many open files" usually suggests serious system resource shortage: either you're not allowed to open any more files (sysadmin-adjustable resource limit) or there is a system-wide resource shortage.

Citrix support says:

http://support.citrix.com/article/CTX102917

----

CTX1020E CDM failed to handle session reconnect for session $1 (error code $2).

Explanation:

The CDM server process was unable safely to perform the necessary

functions for a MetaFrame session which was reconnected. This can be

caused by an internal MetaFrame error, or by serious resource shortage.

Recommended action:

Check the system log for other messages indicating resource shortage,

and attempt to free system resources if this is the cause of the error.

Contact your Citrix support representative.

----

If only you are suffering from this problem, the cause might be the session-specific resource limit: run "ulimit -a" and see the line "open files". The default soft limit is usually 1024 on Linux. If this is not enough for your requirements, run "ulimit -aH" to check the corresponding hard limit. If the hard limit is greater than the current soft limit, you can increase the soft limit with "ulimit -n <new value>". The soft limit must always be lower or equal to the hard limit.

If the soft and hard limits are already equal, the hard limit must be adjusted: on most Linux distributions, it is configurable in /etc/security/limits.conf. Modification of this file normally requires root privileges, and you must logout & login again to make the new setting effective in your session.

If other users and/or system daemons are also suffering from resource shortage, your system might be hitting a system-wide maximum number of files. Run"dmesg": if it contains messages like

"VFS: file-max limit <number> reached"

then you have this problem. You can also use "cat /proc/sys/fs/file-nr" to see the current usage level and the maximum value.

To increase the system-wide maximum number of files, use this command:

sysctl -w fs.file-max=<new value>

You must also add a line to /etc/sysctl.conf to make the change permanent: if you don't, the default value will be restored when you reboot the system.
