[las_users] LAS compare of two variables crashes or hangs server

[Penny Oots <p.c.oots@xxxxxxxxxxxxx>]

All,

I don't know if this is a known LAS anomaly (fancy word for bug).  I did 
not find it in the FAQ or LAS archives.  Matter of fact, it has taken me 
weeks to stumble onto the solution to the crashes or LASserver.pl hanging 
when comparing two months of the same parameter variable.

LAS had no problem displaying single months on one parameter but when the 
'compare two' tab was clicked on the same parameter, LAS would display a 
blank popup and eventually timeout (if we did not run out of swap space 
first and have to reboot).  If I selected the option to cancel the job, I 
would get the message that the job was still active and could not be 
canceled.  The debug_ferret.jnl file always stopped at the same place with 
no error.

While testing, I created the netcdf file with a name of 16 characters plus 
..cdf for the file extension.  This worked correctly.  When I recreated the 
file with a file name of 46 or 55 characters plus the .cdf extension, the 
'compare two' hangs.

I am in the process of recreating multiple files with shorter names.

What is the maximum file name length for a netcdf file to be compared in 
LAS?   A file with a name of 38 characters plus the .cdf extension seems to 
work.

Anyone else run into this problem?
