Description
During our testing, RHEL6 x86 machines are intermittently failing when issuing the following command:
tomcat-vault.sh --encrypt 1 2 (note that the actual values after encrypt are irrelevant)
When trying it manually, I can see that tomcat-vault intermittently hangs, which causes timeout and fail of the test. For example:
[root@rhel6-x86-1650 ~]# for i in {1..10}; do /mnt/hudson_workspace/tomcat-vault-1.1.6/bin/tomcat-vault.sh --encrypt 2 3; done ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::LwuNB5nJZrNHW3EfKDsMvQ== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::SJFNHH04uSjcix4IROG+TQ== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::+i+E6n1XgbT+R3bpmZHOYw== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::CATOf+DjAuQC1JQz1K25Rg== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::cS5iTRkPk8EGcq8BWwrcXw== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= Encrypted value: CRYPT::wakK2dpYYXaHSJQqrVeOrg== ========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ### This is where the hang happened, command became unresponsive ### ========================================================================= ^C========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= ^C========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= ^C========================================================================= Tomcat Vault VAULT_HOME: /mnt/hudson_workspace/tomcat-vault-1.1.6/lib JAVA: java ========================================================================= ^C[root@rhel6-x86-1650 ~]# ^C
I am not sure what is a possible cause. I have tested that this happens only on RHEL6 x86 (x86_64 RHEL6 or RHEL7 did not hang even when I executed the command in a 1..100 range). JDK is failing with both Oracle/OpenJDK 1.8, and OpenJDK 1.7. Given that it fails on these three, I assume it is JDK independent and did not try further JDK combinations.
I have also verified that this is reproducible on vault 1.1.5--same command, when it works for the first time, issuing it several times in a row causes it to hang.
