Why does deploy to tomcat7 via maven hang?

Question

Java

I deploy via tomcat7-maven-plugin . First with the command mvn tomcat7:deploy , and then mvn tomcat7:redeploy .

Uploading : dev.server.ru:8080/manager/text/deploy?path=%2F&up...
Uploaded: dev.server.ru:8080/manager/text/deploy?path=%2F&up... (90924 KB at 9180.5 KB/sec)
[INFO] tomcatManager status code:200, ReasonPhrase:OK

After about 3-4 deployments, everything stops working, viz. Maven shows this step for a long time:

Uploading : dev.server.ru:8080/manager/text/deploy?path=%2F&up...
Uploaded: dev.server.ru:8080/manager/text/deploy?path=%2F&up... (90924 KB at 9180.5 KB/sec)

Although if you go to dev.server.ru:8080 the application is already running and running.
You have to interrupt the work of the CTRL + C
command. And then, when you try to deploy, it freezes at the step:

Uploading : dev.vseplatezhi.ru:8080/manager/text/deploy?path=%...

And only restarting tomcat helps to fix everything.
What could be the problem? And in what direction do you need to dig in order to solve the problem?

Answer 1

Show the jmap -heap $PID command, where $PID is the process of the running tomcat.
Wang that your permgen is running out due to constant redeploys.
