coldfusion - cfdocument tag suddenly throwing "This function should be called while holding treeLock." error -

-

i have application contains form which, until recently, able save pdf using cfdocument. few weeks ago swapped out server. old server running cf 9.0.1. new server cf 10. since then, i've been getting error when try save particular form pdf.

--

an exception occurred when performing document processing. cause of exception that: coldfusion.document.spi.documentexportexception: java.lang.illegalstateexception: function should called while holding treelock.

--

i have page in application saves pdfs fine. it's page that's throwing error. can't find treelock anywhere on web (at least, nothing pertains coldfusion).

has else run this, , if so, how did fix it? thanks!

i started getting error upon promoting new version. rendered content in html. found had forgotten promote image (got dreaded x image). promoted image, cfdocument pdf works again. (i'm using localurl="yes")

in other words, can debug cf errors halt process cfdocument pdf blithely assumes html content supply correct , complete.
