Rapache fail to execute R script occasionally

[masudgh]

Hi
I am using v 1.2.5. I am doing a simple POST to the RApache and trying to run a R script. sometime it does return the result correctly, sometime it doesn't rather return following:
"replacement has 1 row, data has 0"

To verify, I have ran the exact same R script directly under R command line, there was not any issue.

Here is my system info:
sysname Linux
release 3.11.0-23-generic
version #40~precise1-Ubuntu SMP Wed Jun 4 22:06:36 UTC 2014
nodename vb12
machine x86_64
login unknown
user www-data
effective_user www-data

Here is my R info:
platform x86_64-pc-linux-gnu
arch x86_64
os linux-gnu
system x86_64, linux-gnu
status
major 3
minor 1.0

svn rev 65387
language R
version.string R version 3.1.0 (2014-04-10)
nickname Spring Dance

Please help me in this regards. Thanks.

It's rather hard to try to help you without a minimal reproducible example (of the script).
