apreq_parser_run() returns APR_EOF with large uploads

[request4spam <request4spam@xxxxxxxxx>]

Forgive me (and direct me, please) if this is not the best list for such a question -- I searched the list information & this is the best I could come up with.

I'm using libapreq2 to process in-the-stream POSTs in order to detect uploads. Long story short is that I get APR_EOF returned from apreq_parser_run() when uploads/attachments are fairly large (>200k or so; The process works correctly otherwise). Due to this, apr_table_do() does not return information about the actual upload.

Here is my code:

apr_table_t* pPostBody            = apr_table_make(m_pAprPool, APREQ_DEFAULT_NELTS);
apr_bucket_alloc_t* pBucket        = apr_bucket_alloc_create(m_pAprPool);
apr_bucket_brigade* pBrigade    = apr_brigade_create(m_pAprPool, pBucket);

apreq_parser_t* pParser            = apreq_parser_make(
        m_pAprPool, 
        pBucket, 
        contentTypeBuf.data(),
        pfnParserFunc, 
        APREQ_DEFAULT_BRIGADE_LIMIT,
        "C:\\Users\\joeuser\\AppData\\Local\\Temp",    //    :TODO: FET
        NULL, 
        NULL);

//  The entire post data (e.g. HTTP body) is in pData with uiDataLen length
APR_BRIGADE_INSERT_HEAD(pBrigade,
        apr_bucket_immortal_create(pData, uiDataLen, pBrigade->bucket_alloc));
    APR_BRIGADE_INSERT_TAIL(pBrigade, apr_bucket_eos_create(pBrigade->bucket_alloc));

apr_status_t rv = apreq_parser_run(pParser, pPostBody, pBrigade); // rv will be APR_EOF here with ~ >= 200k attachments

apr_table_do(AprPostBodyIterCallback, &iterCbData, pPostBody, NULL); // AprPostBodyIterCallback only gets hit for a couple keys; no upload params/etc.

What am I doing wrong?! Please help!

Thanks,

Bryan
