Tying up loose ends... so many problems later! I started resolving the needed compile deps to run SMTPAppender_SubethaSMTPTest, but never finished. I found that having a DEBUG logger on org.subethamail causes the test to hang, as simple as: <logger name="org.subethamail" level="DEBUG" /> My guess is the tiny bit of extra processing of its messages must cause a race condition to miss reading the response (?). Any chance of adding the timeout attribute to SMTP appender? I still think it is a good idea, and would like to set it. http://jira.qos.ch/browse/LBCLASSIC-220 -----Original Message----- From: logback-user-bounces@qos.ch [mailto:logback-user-bounces@qos.ch] On Behalf Of Ceki Gülcü Sent: Friday, July 23, 2010 11:17 AM To: logback users list Subject: Re: [logback-user] Hang with SMTPAppender On 23/07/2010 5:46 PM, Jeff Jensen wrote:
Hi Ceki, thanks for the reply. Welcome.
Yes, I upgraded to 0.9.24 while investigating this problem. I must have captured the stack before that.
OK.
I wondered about a race condition too. To try mitigate that at SubethaSMTP start/shutdown, I added Thread.sleep(10000) calls after start and before shutdown. There was no change; is 10 seconds long enough to wait to see if a shutdown server is the problem?
Yes, 10 seconds is more than enough.
Any suggestion for setting the timeout value via Logback?
As I mentioned in my previous mail, we also use SubethaSMTP for testing purposes. See SMTPAppender_SubethaSMTPTest [1]. Could you copy and paste SMTPAppender_SubethaSMTPTest into your environment and see if it runs properly? If it runs OK, I suggest comparing the code in SMTPAppender_SubethaSMTPTest with your test code.
