[Exist-open] problem - Node not found

[Slawomir T. <trz...@ma...>]

Hi all,

I'm developing simple java Web Service which uses ExistDb. 
In my application we receive a lot of requests, and insert/delete/query
data into ExistDb. Currently I'm using Exist 1.2.6. 

I connect with exist by xml:db. Sometimes I receive this error :

It is hard to replicate it. When I invoke some stress tests on my web
service ( a lot of requests) this error is thrown. Do you have any
advice ? 

I've attached log of the existDb.

Slawek
