Out of Memory Error with edtFTPjPro 1.3.3

Question

Hi.

We are experiencing OOM error since a while on our server. We use your software (since 2006) as an embeeded component to SFTP files from a server.
Once in a while we see occurence of this problem. Unfortunatly I haven't been able to corrolate this problem to any cause.

As you can see in the javacore below, the OOM occurs when 1gig is requested by one of your class. My assumptions now are either :

1. Encryption/Decryption cause the data to be "inflated" in gigantic proportion ; or
2. Our FTP server sends corrupted message to FTP client

Here are some informations

* edtFTPjPro version: 1.3.3
* JVM vendor : IBM
* JVM version : 1.5
* Processor arch : 64 bits

Answer 1

Hi, can you please send us a log file set to the ALL level of logging - see the User's Guide for more details. Email support at enterprisedt dot com (and zip the file).

Answer 2

I am afraid it's gonna be difficult for us to do so... Our production server is very busy and doing so will generate a huge amount of log. Is there a way to restrict the log size so we don't fill our disk space ?

Answer 3

I guess in the first instance, try a logging level of INFO, which shouldn't generate too much logging. Then email it to us and we'll see if that gives us enough clues (support at enterprisedt dot com). Please zip it first.
