&lt;p&gt;I have a replica set setup with two nodes, both running locally on my development box. The primary is that crashes, the logged message is &quot;Fatal error in v8::Context::New()&quot;.&lt;/p&gt;

&lt;p&gt;The seems to happen always after db.collection.remove() operation where I delete all records from the collection over PHP (mongo 1.4.1). The collection I clear contains only 20-30 small records, no indexes.&lt;/p&gt;</comment>

&lt;p&gt;Thank you for confirming that the ulimit change worked.&lt;/p&gt;

&lt;p&gt;A virtual memory ulimit of 3327200 seems particularly low; it&apos;s probable that your mongod memory footprint has increased enough to tip you over that limit.  Perhaps the limit had been previously adjusted but was reset on a reboot or upgrade.&lt;/p&gt;

&lt;p&gt;Per the &lt;a href=&quot;http://docs.mongodb.org/manual/administration/production-notes/#mongodb-on-linux&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;Linux production notes&lt;/a&gt; in the MongoDB manual, the &lt;a href=&quot;http://docs.mongodb.org/manual/reference/ulimit/#recommended-settings&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;recommended setting for ulimit -v&lt;/a&gt; is &lt;tt&gt;unlimited&lt;/tt&gt;.&lt;/p&gt;

&lt;p&gt;Limits that are set too low may cause operational or performance issues.&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
Stephen&lt;/p&gt;</comment>

                            <comment id="314292" author="stennie" created="Tue, 16 Apr 2013 05:36:21 +0000"  >&lt;p&gt;Hi Alexander,&lt;/p&gt;

&lt;p&gt;Do you have any update after increasing the address space ulimit?&lt;/p&gt;

&lt;p&gt;Thanks,&lt;br/&gt;
