ubuntu 12.04 freeze

so I was getting random freezes on ubuntu where mouse keyboard or anything wont work.  The probability of freeze increases if I start youtube.  Ultimately my colleague recommended upgrading linux kernel following

5 days after the kernel upgrade and no more crash even if youtube is running in background for almost 3-4 hours.

The only thing I had to for was reinstall virtualbox. Now yesterday I had to install guest additions and unfortunately the ubuntu package tried installing virtualbox-guest-additions-iso with old kernel compatibility and it didnt worked.  Anyways for now its not itching me that much and I will scratch it if it become unbearable, due to this I am unable to copy paste between ubuntu host and guest even though I had enabled bidirectional clipboard sharing.


  1. Why not use ubuntu 13.10? Everything works smoothly there.

    1. because 12.04 is a LTS release and 13.10 is fresh out of the oven and only supported for 9 months. As an enterprise company people want to use stable releases to avoid suprises.

  2. Well April's going to dish out 14.04 which is LTS again so 9 months isn't a worry. Well I went with it and hated unity and hence running on gnome 3.10 and I must say 13.10 with all the apps paired with gnome 3.10 rocks. I wonder how 14.04 with mir would be.

    1. haha I hated unity also but now I somehow got used to it because even though I logged in to ubuntu classic lots of simple things skype/pidgin systray were not working properly, instead of trying to spend time figuring it out in busy schedule, I just started using unity.

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.

I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using

    <bean id="transactionManager"
        <property name="dataSource" ref="dataSource" />
        <property name="defaultTimeout" value="30" /> <!--30 sec--->             

or you can override the timeout in the annotation

    @Transactional(readOnly = false, timeout=30)

or if you are doing it programatic transactions then you can do

DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);

 or you can override the timeout for one particular transaction

TransactionTemplate transactionTemplate = new TransactionTemplate();
